Unexpected element - JAXB

Question

We have 4 huge (similar) schemas that i compiled and successfully unmarshalled one xml file with validation turned off.
Problems that I am facing are
1) When I turn on validation, i run in StackOverFlow exception - tried all sorts of memory settings - no luck.
2) When i tried to unrmarshal another XML file that is conforming to 2nd schema, i am getting error messages "Unexpected element".
XML file is well-formed and valid (validated with XML spy).
My understanding is that JAXB wouldn't validate XML file stucture against scheme when validation is turned off. Why is JAXB validating the structure of the XML document?
Java file:
Main class
MyValidationEventHandler veh = new MyValidationEventHandler();
JAXBContext jc = JAXBContext.newInstance( "org.tgslc.advweb.xmlbinding.response:org.tgslc.advweb.xmlbinding.response.FFEL:org.tgslc.advweb.xmlbinding.response.core:org.w3._2001.xmlschema" );
Unmarshaller u = jc.createUnmarshaller();
u.setValidating(false);
u.setEventHandler(veh);
System.out.println("isValidating : " + u.isValidating());
org.tgslc.advweb.xmlbinding.response.CommonRecordCommonline request =
(org.tgslc.advweb.xmlbinding.response.CommonRecordCommonline)u.unmarshal( new FileInputStream( FILE_NAME ) );
org.tgslc.advweb.xmlbinding.response.FFEL.TransmissionDataType trans = request.getTransmissionData();
displayTransmissionDataType( trans );
class MyValidationEventHandler implements ValidationEventHandler
public boolean handleEvent(ValidationEvent arg0)
System.out.println(arg0.getMessage());
return true;
}

JAXB questions should be better directed to the users list of http://jaxb.dev.java.net/
you should subscribe to the 'users' mailing list, then post a question there.
